Application filed July 19, 1803. Serial No. 508,462.

To all whom it may concern:

Be it known that I, NELSON E. RABER, a citizen of the United States,residing at Akron, in the county of Summit and State of Ohio, haveinvented certain new and useful'Improvements in Tire rapping andUnwrapping Machines, of which, the following is a specification,reference being had to the accompanying drawings.

This invention relates to improvements in machines for wrapping tires.

One object of the invention is. to provide a simple and practicalmachine of this character which will be automatic in operation and whichmay also be used for un- Nvra vin the tire after the vulcanizin O s Dprocess.

Another object of'the invention is to provide an automatically operatingmachine of this character which will wrap the tape around the tire firstin one direction and then in the reverse direction.

Further objects of the invention are to provide improved means forsupporting the tire and rotating the same; improved means for mountingand operating the tape spool; improved means for controlling the speedof the tire rotating means; improved means for automatically reversingthe tire rotating means and improved means for instantly stopping thetire rotating means.

Vith the above and other objects in View,

In the preferred embodiment of the invention which is illustrated in thedrawings 1 denotes a bed plate mounted in a horizontal plane uponsupporting legs 2. I The front portion of the bed plate is preferablyformed with a downwardly ofi'set portion 3 in which is secured astationary annular frame 4 forming a support for a rotating annularframe 5 carrying a tape spool 6. The sta-. tionary'frame or annulus 4has the rotatin frame or annulus 5' arranged within it an both of theseframes are made in two halfsections which can be separated to permit atire to be placed within them and upon a supporting and rotating meanshereinafter described. The lower half-section 7 of the stationary frame4 has upon its bottom a shoe 8 which is secured by a bolt 9 in theoffset portion 3 of the frame, as will be understood on reference toFigs. 2 and 7 and the upper section 10 of said frame 4 has its rear endconnected by a hinge 11 to the corresponding end of the section 7. Theother or front end of the half-section 10 of the stationary frame has alug 1-2 notched to receive a fastening bolt 13, which latter is slidablyarranged in a slot formed in-a lug 14; on the front end of the section 7a cam lever 15, as clearly shown in Fig. 7. The half-sections 7, 10 ofthe stationary frame are of angular shape in cross section, as shown inFig. 8, and to the radially projecting flanges of said sections issecured by screws or similar fastenings 16, as shown in .Fig. 8, asectional ring 17. he ring 17 has two-half-s'ections corresponding tothe sections 7, 10 and arranged within it is an annular series ofanti-friction rollers 18 which support and confine the rotary frame oran and carries nylin rical shape and arranged on pivot' nulus 5. Therollers 18, as shown more clearl in Fig- 13 of the drawings, are ofscrews 19 with interposed annular rows of anti-friction cylinders 20. I

The rotary frame or annulus 5 is formed of two half-sections tocorrespondwith the half-sections of the stationar frame so that the tirecan be inserted in an removed from said frame and it is provided with ashouldered portion or flange 21 which prevents lateral displacement.Provided upon the portion of the member 5 projecting from beneath therin 17 is an annular series of gear tee th 22 forming a gear ring whichmeshes with a pinion or gear 23 fixed to a longitudinal shaft 24 onwhich is arranged i Y a bushing 11 to serve as a pintle for the 5 hin e'11. The shaft 24 is journaled in bearing rackets 25,26 rising from thebed late and constitutes the main drive shaft 0 the machine. On thisshaft is mounted a drivnal link or rod to the intermediate portion of ahand lever 31. This leverhas its rear end pivoted at 32 upon the bedplate and'up'on its front end is a hand grip;

The tape spool 6 is keyed, as shown at 33,

to a sleeve 34 rotatably mounted on a pivot 35 and having an annular rowof antifriction rollers 36, as shown in Figs. 8 and 9. Connected to thesleeve 34 by a safety friction clutch device is' a pinion37 which mesheswith an annular row of gear teeth 38 provided upon one edge of thestationary frame 4 and forming a. stationary gear about which the pinion37 travels for the purpose of. winding thetape upon the spool when themachine is used for unwrapping a tire. It will be understood that thepinion 37 is only in mesh with the gear ring 38 when the machine is usedfor unwrapping.

a tire and to permit this pinion to be thrown into and out of mesh withsaid gear 38, the pivot or shaft 35 is provided with an eccentricallydisposed portion 39 rotatably arranged in the frame or annulus 5.

It will beseen on reference to 8 that when the end 39 of the pivot 35 isrotated the portion of said pivot carrying the pinion 37 will be shiftedtoward and from the frame 4 to throw the pinion 37 into and out of=-meshwith its gear. The above mentioned friction clutch connection betweenthe pinion 37 and the spool carrying sleeve 34 is provided to preventthe tape. from breaking and it preferably consists of forming upon thepinion 37 a concentric coneshaped projection 40 which frictionallyengages the wall of a cone-shaped recess in the adjacent end of thesleeve 34. A spring washer 41 is summed between adjusting and jam nuts42 on tlie reduced outer end of the pivot 35 and the outer end of thesleeve for securing the desired frictional contact of the cone 40 withthe recess in which it is arranged. An annular row of bearing balls 43arranged in a cage 44 are preferably provided between twowashers 45located beneath the spring 41 and in a concentric recess at the outerend of the sleeve 34. A

similar arrangement of anti-friction balls and washers is providedbetween the pinion 37 and an annular stop flange 46 provided on thepivot adjacent its eccentric portion 1 39; I also preferably arran ewithin the.

pinion 37 an annular-row of anti-friction rollers 47, which are spacedfrom the rollers'.

36 by a washer 48, as shown in Fig. 8 of the drawings.

The guiding and tension device for the tape spool 6 isshown more clearlyn Figs. 7, l0 and 11 of the drawings andcomprises an annular flange 49provided on the sleeve 34 and having a V-shaped edge to entersimilar-shaped recesses formed in the opposing faces of twosubstantially semi-circular tension brake members 50, 51. These membersare pivoted together at one end, as

shown at 52, andhave their opposite ends formed with o enin to receive aclamping bolt 53 provi ed with a winged adjusting nut 54 and a tensionsprin 55. The mem.- bers 50, 51 are anchored by a bracket 56 havin anapertured end to receive the bolt 53 and interposed between saidmembers, as shown in Fig. 16. The other end of the bracket 56 has anelongated opening 57 to receive a screw 58. arranged upon the rotatingframe or annulus 5. slot 57 allows the bracket 56 to shift when thepinion 37 is thrown into and out of mesh The opening orwith the gearring 38. It will be seen that by adjusting the nut 54 the tension of thebrake members 50, 51 may be varied on the spool carrying sleeve 34. Thebracket 56 and the bracket arm 59 formed on one end of the. member 51provide supports for the pivots of four rollers 60, 61, 62, 63 for thestrip of tape, which latter is denoted by the letter S. These rollersare arranged,'as shown in Fig. 7, and are preferably constructed andmounted substantially as shown in Fig. 12, on reference to which latter'figure it will be seen that the pivot 64 for the rollers -has athreaded end adapted to be screwed into one of the openings in thebracket 56 and arm 59. Antirfriction bearings 65 are also preferablyprovided for these rollers so that the tape will be permitted to runeasily and will be kept free fromgrease which is placed within therollers.

The tire which is indicated by the letter T is supported whilebeing'wrapp-ed by a forming or holding device shown in F ig. 17 of thedrawings. This holding device consists of a core H which is arrangedwithin the tire T and has an inwardly projecting annular flangeformedwith a V-shaped groove. The strip of tape S has attached adjacentto one of its ends a substantially spherical button h which is seated inthe groove of said flange on the core. The tape S extends from the tireupwardly between the rollers 60, 61, around the roller 62, thendownwardly around the roller 63 and from the latter to the spool or drum6. The rollers 60, 61 serve as guides so that the machine can run ineither direction for either the winding or unwinding oper ation. Owingto the manner in which the tape is engaged with the rollers 62, (33, andowing to the arrangement of the roller 63 on thebracket arm 59, whichlatter is in effect a lever, the pull upon the tape will be communicatedto the friction brake device for the spool 6. This variable tensiondevice is provided because less power is required to unwind the tapefrom the spool when the latter is full than when the spool is almostempty. It will be noted that the pull on the tape increases as the spoolis gradually emptied and this increased pull will tenl to open thefriction brake or tension device, thereby maintaining a uniform tensionon the tape. The tire and its holder are supported on two supporting anddriving rollers 66, 67 and are retained thereon by a retaining roller68. These three rollers are of cylindrical form and have annular groovesof substantially V-shape in cross section to correspond to the crosssectional shape of the inner portion of the holder H and in the bottomsof said V-shaped grooves are smaller grooves 69 which allow for the freemovement of the trip lug or button It over said rollers. The supportingand driving rollers 66, (37 are fixed to the front ends of horizontalshafts 70 journaled in bearing brackets 71 on the bed plate, while thethird roller 38 is jonrnaled on a stub shaft projccting from a slide 72having undercut or dove-tailed edges arranged for vertical movement inanupright guide 73 depending from the oll'sct portion 3 at the front ofthe bed platc. Said slide 72 is connected by a link to a fool lever orireadle 74 pivoted intermediate its ends on a bracket 75 secured to thefloor or support on which the the rollerffiS downwardlyand cause thesame to make the tire holder H bear With suiticn-nt friction on thedriving rollers 66, 67,

7 which hutcr are disposed in the same horizontal plane. It will benoted that this arrangement of the rollers allows tires of differentsizes to be handled by the machine.

The two shafts 70 are connected together for simultaneous movement inthe same direction by an endless belt 76 arranged on pulleys at theirrear ends and on one of said shafts is fixed a gear 77 which meshes witha gear 78 fixed to a forwardly and rear-- wardly extending shaft 7 9journaled in bearing brackets 80. Slidably but non-rotatably mounted onthe shaft 7 9 is a friction wheel 81, the periphery of which engagesandis shiftable across the face of a. friction driving disk 82 fixed to oneend of a longitudinally -extending shaft 83' journaled in bearings 84,one of the latterhaving athrust bearing 85 for the other end of theshaft 83, as shown in Fig. 1. The shaft 83 has fixed to it a gear 86which meshes with a pinion 87 fixed to the main drive shaft 24. Thefriction wheel 81 is shiftable across the face of the driving disk 82for the purpose of varying the speed of the tire rotating rollers 66, 07and also for reversing the direction of movement of the same. Said wheel81 has its hub slid-ably arranged on the shaft 7 9- but keyed to thesame for rotation therewith, and rotatably mountediir its hub portion isa sectional collar 88 pivoted in the forked upper end of a shiftingmember 89, the lower end of which latter has a guide sleeve JOwhich isslidable on a guide rod 91 extending in a forward and rearward directionbeneath the shaft 79 and having its ends supported in the brackets 80,as shown in Fig. 3. Upon the interme diate portion of the member orslide 89 is :1 lug 9:2 to which latter is pivoted one end of a link 93having its other end pivoted to one arm 94 of an angular lever-95. Thelever 05 has its angle fixed to a vertical pivot or shaft 06 rotatablein upper and lower bearings on a bracket 97 secured to the bed plate andon the extreme upper end of said shaft is fixed a hand lever 98 by meansof which the lever 95' may be shifted. The second arm 100 of'said leverprojects forwardly and has at its extremity a transverse portion formedwith an arc-sha ped slot 101. The latter receives an upright screw stud102 pro ecting from an arm 103 which is loosely mounted on the pivot orshaft 96 beneath the arm 100 and which has at its free or front end atransverse head 10%. adapted to swing above the top of a guide casing105-secured on the bed plate and containing a spring projected catch ordog 106. The-latter is in theform of a vertically sliding pin, asclearly shown in Fig. 5 of the drawings, and its projecting upper end isadapted to enter either one of two openings or seats 107, 108 formed inthe ends ofthe cross portion or'head 104 of the arm 103. The catch ordog 106 is, therefore,

adapted to lock the arm 103 in either of two positions and the arm isadj ustably connected to 'it by means of the-screw stud 102 shifted thefriction'wheel 81 will be shifted longitudinally on the shaft '79 andthence across the face of the driving disk 82 so that by tightening thenut 109 after the friction disk has been shifted to an adjustedposition, it will be maintained insuch position, thereby determining thes eed of the driving rollers 66, 67 for the tire. The parts abovedescribed are also so proportioned that when a tire is tobe wrapped thecatch 106 engages the seat 107 at one end of the head 104 and the wheel81 will be at or adjacent to one edge of the disk 82,-according to theadjustment of said. wheel, and that when a tire is to be unwrapped thecatch 106 is engaged with the seat 108 in the other end of the head 104.The shifting movement of the head 104, when the catch 106 releases it,is preferably effected by providin a weight 110 on one end of a cord or0t er flexible element 111 which asses over a guide pulley 112 and hasits ot er end detachably connectedto a stud or button 113 arranged atthe center of said head 104. The ulley 112 is journale'din a block 114which as a swiveled connection with the bed plate, as shown in Fig. 4,and which has a tubular portion to receive the cord 111, therebyallowing, the weight 110 to hang beneath the bed plate 1.

* The pulley block 114 is swiveled sothat the cord 111 when detachedfrom' the pin 113 may be engaged with a similar pin or button 115arranged in the aperture of an angularly projecting arm 99 provided onthe pivoted end of the armor member 103. The cord 111 is thus shiftedwhen a tire is to be unwrapped, as will be hereinafter explained. A Thecatch pin or dog'106 is projected upwardly by a coil spring 116 arrangedwithin its casing 105 and its lower end is adj ustably connected, asshown at 117, to one arm of a bell crank 118 which is pivoted beneaththe bed plate and has its other arm connected by a link 119 to thecorresponding arm of a similar bell crank 120. The latter is alsofulcrumed beneath the bed plate and has anarm connected by a link 121 toa trip lever 122. The link 121 is preferably made ad- -justable, asshown in Fig. 4, by making it of a rod having its ends formed with rightand left hand screw threads which engage similar threaded socket members123 pivoted to the bell crank and lever 122. A hand wheel'124 is fixedto the link rod 121 and-a lock nut 125 in the ,form of a hand wheel isarranged on the upper threaded end of the link rod and adapted to bescrewed against the upper socket member 123 to retain the.

arts in adjusted position. The trip lever 122 is fulcrumed intermediateits ends at 126 on the part of one of the bearin%s 71, as .shown' inFigs. 1 and 2. Said trip-' ever extends longitudinally and its free armis adapted to project into the open frames 4, 5 so as to be en aged andactuatedby the tri projection or utton h on the the holder To effectthis latter result, said free end of the trip lever is provided with aforwardly extending stub shaft 127 on which is journaled a roller 128which lies in the path of V.

the trip button b so that as the tire and-its holder are rotated on therollers 66, 67, 68

said button It will :ike the trip roller 128 to shift the trip lever122, thereby causing the link. and lever connections above described toretract the catch or dog 106. f;

Foithe purpose of quickly-stopping-the movement of the rollers 66, 67, Iprovide means for shifting the friction wheel'81' to the center of thedriving disk 82, such means consisting of slidable sleeves 129 arrangedon the shaft 79 on opposite sides of the wheel 81 and having annulargrooves in which are arranged sectional collars 130. 131 denotes twoangular levers having forked end's slotted, as shown in Fig. .1, for thereception of screws which are arranged in the sectional collars 130,washers being arranged on said screws, as shown.- This construction.provides a slot and pin connection between said parts and prevents thesleeves from rotatmg. These levers are crossed and are pivotally unitedat their point of lntersection by a .pivot 132 rising from a supportingbracket 133 on the bed plate. The opposite ends of said levers 131 areconnected by links 134 to a cross bar 135 centrally pivoted on a bolt130 which carries a roller 136' and is slitlabltein a slotted arm 137 ofthe' bracket 133, as shown in Figs. 1 and 4 of the drawings. This linkconnection between said levers 131 is provided to cause them to haveuniform movement when actuated by a spring 138 in the form of a wirehaving its central portion coiled and retained upon the pivot 132 by anut 139 and which has its ends connected at 140 to said levers 131.Pivoted to a lug on the forked arm of one of the levers 131- is anadjusting link 141. The forward end of this link is longitiidinallyslotted to receive a screw stud 142 I15- ing from a bracket 143 on thebracket 80. A clamping nut in the form of a hand wheel 144 is arrangedon the upper end of the screw stud 142 to clamp the link 141 in adjustedposition. It will be seen that .when

the nut 144 is loosened theslotted forward 1 25- too ' fastening bolt atthe free ends of the frame sections 4 is then thrown up and said boltmoved outwardly to free the upper 'section 10, which latter togetherwith the upper section of the rotating frame 5 may be raised upwardly topermit the tire to be placed within said frames, it being understoodthat the t-ire is placed in its holding device H. After" the tire hasbeen arranged upon-the rollers 66, 67, 68 as above explained, thehalf-sections of the frame 4 are locked together and the free end of thestrip of fabric or tape 8- on the spool 6, after being passed betweenthe guide rollers, has the button it which it carries inserted in thegroove of the core H. It will be understood that when the machine isused for winding or wrap ing the tape on the tire, the pinion 37 will eout of mesh with the gear 38. With the tire and tape thus applied andthe parts of the machine in the position shown 'in Figs. 1, 2 and 3, thelever 31 is shifted to actuate the clutch 28 and thereby lock the beltpulley 27 to the main drive shaft 24 so that the latter will be rotatedand its motion will be imparted through the gears 23', 22 to therotating frame or annulus 5. The latter moves the tape spool around thetire. The tape S is caused to be spirally wrapped on the tire by therotary movement of the latter which it receives through the rollers 66,67, it being understood that the main drive shaft 24 imparts its motionthrough the gears 87, S0 to the shaft of the friction disl; 82 and thatthe movement of thelat'ter is'imparted to the wheel 81 .and hence itsshaft79 which is geared to one of the roller carrying shafts 70. hen themachine is thus started the wheel 81 will be at or adjacent to the -fafside of the disk 82, its speed being governed by its position on saiddisk and such position being determined by the adjustment of the lever95 with respeet to the arm 103. It will be noted that the crossportion'or head 104 of the arm 103 has its opening 107 engaged by thecatch 106 so that the weight 110 will be held elevated and cannotactuate the arm until the tires make one complete revolution and thetrip button it actuates the trip lever 122 .to cause the catch 106 to beretracted. When the latter happens the weight 110 causes the lever 95 tobe shifted for the purpose of bringing the friction wheel 81 to theopposite side of the drivin disk 82, thereby reversin the direction 0movement of the tire so t at the tire-- will be cross wrapped, it beingnoted that the tape s 001 continues to rotate in the same directlon.After the tire has made its second complete revolution the nuts 109 and144 are loosened to release the link 141 and the rotation of, the tire.

When it is desired to unwrap tape from 'the tire,.the latter is placedin position on the rollers 66, 67 68 and the free end of the tape isattached to the spool 6 by wrapping the tape one or more times around itor otherwise fastening the tape. The eccentrically mounted .pivot forthe s 001 6 is then shifted to cause the pinion 3 to mesh with the gearring 38. The lever 95 is shift- ;ed so that the catch 106 engages theopen-'- ing or seat 108 in the head 104 of the arm 103 and the weightcord 111'is attached to the button 115'on the arm 99 of said arm 103.-When the parts are, thus adjusted the machine is set in motion by meansof the lever 31 and the unwinding operation Will by substantially thesame as the winding operation with the exce tion that the spool 6 willbe rotated to Win the'tape thereon It will be notedthat when the machineis used either for winding or unwinding, the

catch 106 is in one of the two seats of the head 104 so that when thetire has made one complete revolution and the button it trips the lever122 to cause the catch 106 to free the head 104, the weight 110willswing said head and consequently shift the friction wheel 81 across thecenter of the friction disk but said catch will not enter the other seator opening in the head 104. The weight-110 will hold the friction. wheel81 in its shifted position until the tire has made a second revolutionin the opposite direction, whereupon the machine is manually stopped, asabove explained. v
